3D target array for pulsed multi-sourced radiography

摘要

The various technologies presented herein relate to the generation of x-rays and other charged particles. A plurality of disparate source materials can be combined on an array to facilitate fabrication of co-located mixed tips (point sources) which can be utilized to form a polychromatic cloud, e.g., a plurality of x-rays having a range of energies and or wavelengths, etc. The tips can be formed such that the x-rays are emitted in a direction different to other charged particles to facilitate clean x-ray sourcing. Particles, such as protons, can be directionally emitted to facilitate generation of neutrons at a secondary target. The various particles can be generated by interaction of a laser irradiating the array of tips. The tips can be incorporated into a plurality of 3D conical targets, the conical target sidewall(s) can be utilized to microfocus a portion of a laser beam onto the tip material.

1. A system comprising:
a first target, the first target comprising a first tip material, wherein the first tip material forms a conical solid comprising:
an apex;a circular base; anda lateral surface joining the apex to a perimeter of the base, wherein at least one photon in a laser beam impinges upon the base and enters the first tip material to facilitate formation of at least one of a first x-ray photon or a first particle, wherein the first x-ray photon is emitted from the apex in a direction on-axis to an axis which passes through the apex and about which the base has rotational symmetry.
